Qt 5 QML Intermediate: Interfacing to C++

Learn how data converts between C++ and QML, translating basic types—string, date, number—and sequence types like lists and vectors, then map variant lists, maps, and structures to the QML side.

Learn how C++ basic types map to QML types and exchange data via signals and slots, including strings, URLs, colors, fonts, dates, and geometric types.

Explore how string, date, and number types transfer between C++ and Quark, including JavaScript date conversion, string arguments, and localization of date, time, and numbers.

Explore localizing dates and numbers in Qt 5 QML using date string methods, date to locale, and from local date string, with examples for German, French, Chinese, and English locales.

Convert c++ vectors and lists to QML arrays. Send data from QML to C++ and retrieve it back to display, using a CP class and QML context property.

Learn to pass QVariantList and QVariantMap between Qt C++ and QML, converting them to JavaScript arrays and objects, and invoke JavaScript from C++.

Review the Q to C++ data type mappings and how the html engine handles seamless transformations, including color, string, date, number, localization, sequence mappings, and variant lists and maps.

Develop a REST API client using QNetworkAccessManager to fetch jokes, parse JSON, and feed data to C++ and QML for dynamic display and removal.

Learn to download HTTP data from the internet with QNetworkAccessManager, QNetworkReply, and QNetworkRequest, parse the JSON value array for jokes, and expose results to QML.

Feed internet data into QML by building an HTML interface, exposing a C++ model via context properties, and initializing the engine to synchronize data with a list view.

Recaps the version one API client, using the network access manager to fetch HTTP data as JSON and bind it to XML via context properties, enabling updates for list views.

Expose C++ data to QML with a custom type, define and use objects and list properties, and learn about inherited, default, grouped, and attached properties, property value sources, and animations.

Register custom C++ types for QML using QML register type and expose properties via Q_PROPERTY, then implement a counter class with signals and a timer to start and stop.

Expose your C++ enums to QML by decorating them with Q_ENUM and registering the type, then access values like information, warning, debug, and message in QML.

Update the qt 5 qml intermediate counter demo to use an enum to control counting direction, exposing a counting class with qproperty and signal to qml, and preventing html instantiation.

Explore creating object and list property types from C++, exposing them to HTML components, including a football team model with players, setters, getters, and list management.

Design and expose a football team in C++ to QML as a list property, wrapping a vector of players with append, count, at, and clear operations.

Learn to work with inherited types from C++ classes and reflect them to HTML, creating striker and defender that extend a player class and registering them for QML and XML.

Enable default properties for C++ classes exposed to XML to allow adding players to teams without explicit property assignment, using the Q_CLASSINFO macro and default property settings as syntactic sugar.

Explore grouped properties in Qt 5 QML by wrapping player attributes in a details class, exposing it to QML, and accessing height, weight, and speed in the UI.

Learn to implement attached properties in Qt 5 QML to add timing features to items via a timer and attaching class, with interval and running properties and timer out signals.

Create a custom C++ class that inherits QML property value source, implements setTarget, and updates a QML property using a timer-driven random number generator with a max value.

Compare multiple registration methods to expose C++ types to QML, including register type for instantiation, uncreatable types, and types used as left-hand side of property binding.

Recaps how to register C++ types for XML and HTML exposure, model objects with list and default properties, and use attached properties and property value sources in Qt QML.

Explore practical ways to interface XML with C++ in Qt 5 QML, using context properties and objects, QML register types, and property features, with practice and documentation guidance.
